Application filed May 21, 1907. Serial No. 374,835.

fo all whom it may concern:

Be it known that I, GEORGE Fnnnnnick RENDALL, a subject of the King of Great Britain, residing in the city and county of New York, State of New York, have invented a new and useful Car-Vheel Axle and Bearing, of which the following is a specication.

My present invention consists of a novel construction of sectional axle and a novel construction of bearing therefor, whereby the wheels carried by different sections may rotate at different rates of speed and adjust themselves to curves in the construction of the roadbed.

It further consists of a novel construction of a bearing in which the axle is mounted, which is adapted to contain a suitable lubricating material, in which the axle can rotate without the lubricating material working out of the bearing.

It further consists of a novel construction of a bearing and sectional axles in which the inner end of each section is provided with a ball or disk and with these balls or disks, an independent ball or disk is adapted to co-act.

It further consists of a novel construction of a bearing and sectional axle in which the wheels carried by different sections are permitted to rotate at different rates of speed and in which the strength and rigidity of of which my invention consists can be va-A riously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein set forth.

Figure 1 represents a sectional view of a car wheel axle and bearing embodying my invention. Fig. 2 represents a 'section on line v Fig. 1. Fig. 3 represents a section on line '1f-y, Fig. 1. Fig. 4 represents a section on line .Q -z, Fig. 1.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :-1 designates the floor of the car or a spring frame of any usual or conventional construction to which the bar 2 is secured in any suit-able manner.

3 designates a box or casing having flanges 1 extending therefrom which are provided with apertures 5, whereby said box may be rigidly secured by means of any suitable fastening devices to the bar 2.

The box or bearing, in the present instance, is composed of sections, the upper box having apertured flanges G extending therefrom adapting the same to be secured to the apertured fianges 7 of the lower section 8 of the box or bearing. In this bearing, the shaft 9 is adapted to rotate, it being noted that the bearing 1() is formed at each end of the box.

11 designates a collar or washer secured to the shaft 9 or to the car wheel 12 which is fixe'dly mounted on the shaft 9, said collar or washer having a flange 13 extending therefrom which extends into the recess 14: in the ends of the box but does not come into contact with the main bearing, but serves the purpose of preventing the escape of the lubricant from the chambers 15 formed by the bearings 10 and the internal flange 16, said flange 1G forming when the parts are in.

assembled position, an internal chamber 17 into which the ends of the shaft 9 extend.

18 designates a bearing block provided with a fiange or projection 19 which engages a slot or recess Q() in the upper' portion of the bearing 3, it being understood as most clearly shown in Figs. 3 and Llthat this bearing comprises the se1ni-cylindrical bearing member with which the shaft 9 .coacts to support the weight of the car. In the present instance the outer, ends of the bearing block 18 are provided with collars 21 which, when the parts are assembled, are located intermediately of the depending flange or ring 16 and the shaft 9, as will be readily apparent by reference to Fig. 1.

22' designatesa collar or counter-poise mounted near the inner ends of the shaft 9 and within the box 17.

23 designates a ball or disk integral with or secured to each shaft 9 between which a ball or disk 24k is located, said central disk being adapted to engage with the disk carried by each section of the shaft, it being noted that the lubricant contained in the chamber 17 may pass therefrom, through the channel or passage 25 into the chamber 15.

Since I provide a chamber 26 upon the bearing A10, it will be apparent that all the bearing parts of the axle will be suitably lubricated under all conditions.

that all the frictional parts work within a closed oil or grease box and that means are also provided to confine the lubricating material in its proper place.

Owing to the manner in which the upper bearing block 18 is secured with respect to the upper portion of the box 3, it will be apparent that any rotation of said bearing block will be positively prevented.

It will now be apparent from the foregoing that I have devised a novel and useful ,construction Yof axle bearing'and axle espe-Y cially adapted to be employed in conjunction with car wheels and which embodies the features of advantagev enumerated as desirable 1n the statement of invention, and while I have, in the present instance, shown and described the preferred embodiment thereof which gives in practice satisfactory and reliable results, it is to be understood that it is susceptible of modification in various particulars without departing from the spirit and scope of the invention or sacrificing any ofV its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a device of the character described, a sectional axle bearing having a plurality of'oil chambers, semi-circular bearing blocks non-rotatably carried by the upper of said sections, 'a sectional axle engaging said bearing blocks, disks secured to the inner ends of said axles, a counterpoise on each axle in proximity to the disk thereon and located within one of the oil chambers and an'independent disk frictionally engaging therewith. Y

2. In a device of the character described, the combination with an axle bearing having a central oil'chamber and an'oil chamber on opposite sides thereof and communicating by a port with said central oil chamber, of a semi-circular bearing block nonrotatably mounted in each of said bearing chambers, an axle section engaging each block and extending into said central chamber, a counterpoise mounted near the inner end of each axle section, a disk at the end of each axle section, and an independent disk frictionally engaging the disks carried by said axle sections.

3. In a device of the character described, the combination with an axle bearing having a central oil chamber and an oil chamber on opposite sides thereof and communieating by a port with saidv central oil chamber, of a semi-circular bearing block non-rotatably mounted in Vthe upper portion of each of said oil chambers, an axlesection engaging each block and extending into said central chamber, collars mounted near the inner end of each axle section, a disk at the end of each axle section, an independent disk frictionally engaging the disks carried by said axle sections, and means including washers mounted on said axle ksections for preventing the escape of lubricant from said` bearing. g

4. In a device of the character described, the combination with a sectional axle bear-- ing having a centrally located oil chamber and an oil chamber on opposite sides Vof said first chamber, of a bearing block non-rotav tably mounted in the upper portion of each of said chambers, lubricatingk material in said chambers, an axle composed of sectionsf in said chambers, the inner ends of said axle terminating in said central chamber, a disk carried at the inner end of each axle, an independent disk having' frictional engagement with said disks, Yand means for i limiting the longitudinal movement of said axle sections. y Y

5. In a device of the character described, the combination witha casing provided with a central oil chamber and end oil chambers, the upper Yportion of said end chambers-having a slot therein, a bearing block having a projection engaging said slot, an axle composed of sections in said end chambers, the inner ends of said axles terminating in said 'Y' central chamber, a disk carried at the end of each axle andan independent disk having frictional engagement with said disk.

6. In a device of the character described, the combination with a sectional axle bearing having a centrally located oil chamber and an oil chamber on opposite sidesof-said first chamber, a semi-circular bearingY block mounted in each of said chambers and having means thereon adapted to interlock with the upper portion of said axle bearing, an axle composed of sections located in said chambers and engaging said bearing block, the inner ends of said axles terminating withinsaid central chamber, ka .disk at the "i end of each axle section and a counterpoise carried by each axle in proximity to the end disk thereon. i
